[SOLVED] Simple question probably...

[hazuki7]

Hi all. I am following a tutorial on GTK and I can't compile a simple hello world program. Getting Started. I am supposed to compile using

gcc base.c -o base `pkg-config --cflags --libs gtk+-2.0`

. When I do this I get the following output:

Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
sauce.c:1:21: error: gtk/gtk.h: No such file or directory
sauce.c: In function ‘main’:
sauce.c:6: error: ‘GtkWidget’ undeclared (first use in this function)
sauce.c:6: error: (Each undeclared identifier is reported only once
sauce.c:6: error: for each function it appears in.)
sauce.c:6: error: ‘window’ undeclared (first use in this function)
sauce.c:10: error: ‘GTK_WINDOW_TOPLEVEL’ undeclared (first use in this function)

This means I need to install gtk right? I downloaded the .tar from ftp://ftp.gtk.org/pub/gtk/2.12/gtk+-2.12.6.tar.bz2 and I did a

./configure

within the directory only to get the output:

No package 'glib-2.0' found
No package 'atk' found
No package 'pango' found
No package 'cairo' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables BASE_DEPENDENCIES_CFLAGS
and BASE_DEPENDENCIES_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I now ask how to proceed. How do I install these 4 packages?
I can't find them by typing something like this

sudo apt-get install cairo

Thanks for your patience. I'm new to the whole ./configure, make, make install thing.

[smolloy]

Have you installed build-essentials?

sudo apt-get install build-essentials

[hazuki7]

Yeah, build-essential is installed. I still can't progress any further in this installation.

[smolloy]

I'm not sure, but this link might be what you need.

[hazuki7]

Thanks smolloy. Problem solved.
